In my opinion the custom lighting you made was overdone to the point where it felt like it was put there just because you could put it there. And I also found the key hunting part to be tedious, boring, and pointless. You should never have it so that you run from Room B, get key, Room E, key, Room A, key. It just removes the purpose of it if there is nothing to the rooms. After two room they all felt the same.

thx for this critic, I'll try to change this "key-problem"
but the point of the lights is they must be everywhere, =)
